My perfect Naruto ending would start with Hashirama explaining to Sasuke the meaning to be a shinobi and to have a clan. Despite sasuke still not being certain the meaning of it asks for Orochimaru and the hokage to join the war. Once Orochimaru and the hokage arrive in the battlefield Minato tells Naruto to go and find Sasuke, while he and the other hokage deal with the situation along with the five healed kage that arrive on the scene. Naruto agrees and follows Sasuke while Minato confronts Obito and Hashirama fights Maddara. Naruto and Sasuke meet at the valley of the end and they start fighting, during the fight Sasuke awakens his perfect susanoo, despite that, after a long battle he loses to Naruto. But Naruto decides to let sasuke live because he was his friend and no matter what he did he would always be, and so he leaves sasuke in the ruined valley of the end thinking about his friends words.
In the battlefield the hokage start being defeated as the juubi enters full power mode. Maddara defeats Hashirama with his new powers and despite defeating Obito, Minato refuses to kill his once student.The hokage and a Orochimaru who wants to redeem itself by one final act, try to hold the juubi giving the alied shinobi forces a chance to escape to the leaf village, but all are defeated by a bijuu dama, except Minato who teleports in the last seccond. He meets naruto and talks to him about the previous battle and gives Naruto his kunai saying that it will futurely aid him before dying again. Naruto returns to te leaf where he is healed and decides he must take on the juuubi alone, promising to return alive, meanwhile, Maddara betrays Obito by taking his life force and leaving him for dead.
Naruto tries to battle the jinchuriki maddara, but his enemy is to strong. Sasuke arrives to help him in the last moment and after a heated battle Maddara losses control of the juubi.Obito apears and tries o use the technique the rikudou senin used to separate the juubi into ten pieces but claims the beast is too strong and it must be destroyed to be separated before dying.
Naruto and Sasuke make a ultimate combined rasengan which they clash against the juubis strongest bijuu dama, they win ,kill the beast and escape the explosion of the bijuu dama by using the flying thunder god technique giving to naruto by his father. Naruto and a Sasuke go back to the leaf. Naruto is welcomed by Hinata with a kiss and they stay togheter as sasuke apologizes himself to sakura who accepts it and so the two stay togheter too. tsunade gives her hokage position up to Naruto and Sasuke is pardoned because of his redemption in the final battle.
